In this article, we present the mathematical model of the permanent magnet synchronous motor (PMSM) permitting the simulation of its dynamic behavior under the MATLAB/SIMULINK environment. This model is based on the Park transformation. This paper proposes a realization of robust speed and current control for the PMSM using a PI-Regulator with and without a Luenberger observer. The simulation results show the very good decoupling between the torque and the stator currents. Thus the presence of the observer improves dramatically the performance of the PMSM in particular the response time and overshoot of the torque.
